Description
Technical field
The invention belongs to agriculture fruit tree fruit thinning technical field, relate to a kind of fruit thinning technology of longan young fruit period, specifically a kind of longan fruit thinning agent.
Background technology
Longan (DimocarpuslonganLoureiro) is aiphyllium, and its fruit---longan and lichee, banana, pineapple are all the large precious fruit in south China four.Longan under normal circumstances fruit-setting rate is extremely strong, have the impression of " liking really not stint tree ", and the longan of golden mean of the Confucian school tree body, each fruit ear can tie more than 40 fruits, and the every fringe of strong tree of Management put can tie more than 70.Excessive fruit burden, can cause crown texture to decline, simultaneously because fruit amount also can cause greatly that single fruit weight is low, poor quality, therefore often needs to carry out fruit thinning at the young fruit period of longan in production.Knowhow shows, golden mean of the Confucian school longan retains 30/fringe, strong tree reservation 50/fringe left and right fruit is advisable, and namely wants fruit thinning 30% ± 2% to be best fruit thinning state, is so just conducive to improving longan single fruit weight and quality, facilitate final-period management, be also conducive to promoting fruit price simultaneously.
In production, artificial fruit thinning is mainly utilized to the fruit thinning mode of longan young fruit period, namely fruit thinning personnel wipe out with the unnecessary fruit of scissors to each fruit ear of longan young fruit period, workload is large, efficiency is low, time is long, if fruit thinning is not in time then to the growth of longan fruit, the formation of output and high quality fruit all has impact, moreover artificial fruit thinning easily causes because of human factor, and fruit thinning is excessive or fruit thinning is not in place, affect the income of orchard worker, be unfavorable for the development of longan mass-producing, have again, artificial fruit thinning can only for more small-sized longan, also inapplicable to larger tree-shaped longan.At present, form scale in the plantation in longan producing region, fruit thinning time Relatively centralized, fruit thinning phase artificial demand is large, and fruit thinning is costly, and also higher to the skill set requirements of fruit thinning personnel.
Along with the development of science and technology and the rise of labor cost, replace artificial input will be the most potential future thrust of fruit growing with change control.The relevant report about longan fruit thinning agent is not yet found through retrieval.
Summary of the invention
The object of the invention is to provide a kind of longan fruit thinning agent for the deficiencies in the prior art, according to longan fruit load regulation mechanism, medicament is carried out scientific compatibility, good fruit thinning requirement can be reached, effectively improve fruit thinning efficiency, solve the problems such as existing artificial fruit thinning labour intensity is large, efficiency is low, it is high to spend, weak effect, to efficient orchard management, there is important directive function.
The technical solution adopted in the present invention:
A kind of longan fruit thinning agent, be that urea, diflubenzuron, amino acid and water are mixed and made, wherein the content of each component is by mass percentage: urea 10%, diflubenzuron 0.1 ‰ ~ 0.2 ‰, amino acid 0.13 ‰ ~ 0.17 ‰, surplus is water.
Longan thank spend after be the fruit thinning phase within the scope of 15 ~ 45 days, all can fruit thinning.Spray the longan tree crown in needing fruit thinning with liquid medicine provided by the present invention (longan fruit thinning agent), being sprayed onto drips is advisable.After medicament sprays 10 days, manually longan 2 grades of branches are vibrated, promote that weak fruit comes off, reach the object of fruit thinning.
The present invention is according to longan fruit load regulation mechanism, by urea, diflubenzuron and amino acid carry out scientific compatibility, effectively weak fruit is removed, retain the fruit that power of bearing fruit is strong, good fruit thinning requirement can be reached, fruit thinning efficiency is improved under the prerequisite of management work not affecting the longan later stage, and operable time segment limit is longer, solve existing artificial fruit thinning labour intensity large, efficiency is low, spend high, the problems such as weak effect, have easy to operate, effective, the features such as cost is low, after fruit thinning, longan fringe type is moderate, single fruit is great, commodity rate is high, to efficient orchard management, there is important directive function.

Test:
By above-described embodiment gained longan fruit thinning medicament respectively with Hainan main breed " stone gorge ", " Chu Liang " etc. for experimental subjects, carry out fruit thinning test at longan growing area.In different zones, random choose fruit ear in different fruit tree, each medicament carries out fruit thinning process, repeats 4 times.Manually longan 2 grades of branches were vibrated respectively at 10 days, 15 days after spraying medicament, fruit number is stayed in calculating, statistics fruit drop rate, adopts gel diffusion method to measure fruit abscission index (carpopodium absciss layer Key Hydrolytic Enzyme Activity), with blank (not dispenser agent) for contrast simultaneously.The investigation of fruit drop rate with the initial fruit ear amount of bearing fruit for 40-50 grain fruit ear is for respondent, different agents process on the impact of longan fruit fruit thinning situation and the index that comes off in table 1, table 2.
The fruit thinning situation of table 1 different agents process
The different fruit thinning chemicals treatment of table 2 is on the impact of longan carpopodium absciss layer Key Hydrolytic Enzyme Activity
Illustrate: enzyme assay adopts gel diffusion method (Agricultural University Of South China's journal, 2012,33 (2): 175-177.Yang Ziqin, 2011) measure, cellulase activity unit Dmm, hemicellulase activity unit Dmm.
Above-mentioned experimental result shows: weak fruit can remove by longan fruit thinning agent provided by the present invention (embodiment one, two, three) effectively, retain the fruit that power of bearing fruit is strong, and after fruit thinning about 15 days, shedding situation is basicly stable, overall fruit drop rate controls 30 ± 2%, longan fringe type is moderate, reaches best fruit thinning state.Simple employing urea soln (embodiment four) carries out fruit thinning, and during fruit thinning 10 days, fruit drop rate is comparatively large, and fruit drop rate increases further after 15 days, can not control overall fruit drop rate better, belong to fruit thinning excessive.The fruit thinning agent (embodiment five) of simple employing diflubenzuron, amino acid preparation carries out fruit thinning, and fruit drop rate, even lower than blank, plays the effect of fruit retention on the contrary, belongs to fruit thinning not in place.When by urea, diflubenzuron, amino acid with the use of, adopt the preparation of urea (embodiment six, seven, eight, nine) of different concns to carry out fruit thinning, its fruit drop rate is too low or too high, causes that fruit thinning is not in place or fruit thinning is excessive.The data judging that the difference of above-mentioned fruit drop rate can spray the longan carpopodium absciss layer Key Hydrolytic Enzyme Activity (cellulase activity and hemicellulase activity) of rear mensuration from different fruit thinning medicament obtains, after fruit thinning, the numerical value of cellulase activity and hemicellulase activity is larger, the probability that fruit departs from carpopodium is higher, show thus, longan fruit thinning agent provided by the present invention, by urea, diflubenzuron and amino acid carry out scientific compatibility, effectively weak fruit is removed, retain the fruit that power of bearing fruit is strong, good fruit thinning requirement can be reached, solve existing artificial fruit thinning labour intensity large, efficiency is low, spend high, the problems such as weak effect, to efficient orchard management, there is important directive function.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
